Dog issues and the HOA

It all depends on state statutes and local law, but ultimately the important document that will be the authority on what the Association can do is the Covenants and Restrictions document that *should* be recorded in the public record. (at least they are here in Florida)

If you don't have your copy (you should have gotten one when you closed on your house/condo/villa if you own it) and it is recorded, if you go to your County's website, often you can actually access documents like that in PDF format and print them out. 

If not you might have to go TO the county offices and copy them (laborious and usually expensive), but it's probably the starting point.  In other words, it's probably not a state law that it's illegal for him to be in the pool, but I'd bet it IS a violation of the Cov & Restrictions.

To add more heat to the broth ... if you *don't* do anything then that lends credibility to the other guys defense of "no one ever really did anything about it so i thot it was ok".  And I've seen idiots like this successfully defend themselves despite rules and regulations IF no one makes them toe the line.

Such are the things that make "normal" people become active in their associations (and it can be a thankless job).  But as I said in the email, just nag everyone to copy, copy, copy .. keep notes and records.  If you speak to someone at the city or county write down whom they spoke to, what time/date, etc.  And any communication that goes to this guy needs to be documented -- OVERLY so.  You don't *just* send it certified because they won't bother to go get it.  You send it (and mark the original, deliverable copy) "via U.S. Regular Mail, and Certified Mail/RRR" -- it's overkill but that and the postal receipt gives you 'proof'. 

That proof need never lead to 'suit' BUT if he thinks your association is organized enough to keep track of the paper and do it legally, he may be less inclined to diss it. 

AND someone like that makes your association dues higher -- because next year's dues have to factor in how much it COST to bring pressure to bear on this guy **as well as** the increased cost of pool maintenance to repair the filter abused by doghair. 

And heaven help you if the dog bites someone.

People like that tend to be singularly selfish, and he ought to be thinking of his property values and preserving his rights as a dog owner or he'll get everyone's 'rights' curtailed.

What about getting a signed petition from your neighbors to the effect of "you're annoying us, please stop"? You could send it certified mail and still have it be an informal complaint - just the neighbors speaking their mind - and then he'd have no "I didn't know it bothered anyone" kinds of excuses.
